A multiverse hiding in the Large Hadron Collider

There are several versions
of multiverse theory. The version I am going to discuss here is derived from
string theory and the notion that there are many extra dimensions that we don't
have access to (just like Matthew McConaughey in the fifth dimension in
"Interstellar"). Some physicists think parallel universes are present
in those extra dimensions. This multiverse notion is testable too. Physicists
will be looking for mini black holes when the Large Hadron Collider restarts
this month. It's impossible for the LHC to generate any sort of black hole that
would be remotely unsafe, but this theory suggests that microscopic black holes
that vanish almost instantly could be produced from the high-power particle
collisions in the LHC.

The existence of black
holes would specify that gravity from our universe is leaking into extra
dimensions. Physicist Mir
Faizal told Phys.org "As gravity can flow out of our universe
into the extra dimensions, such a model can be tested by the detection of mini
black holes at the LHC. We have calculated the energy at which we expect to
detect these mini black holes in gravity's rainbow [a new theory]. If we do
detect mini black holes at this energy, then we will know that both gravity's
rainbow and extra dimensions are correct." That would be exciting
confirmation for both string theory and parallel universes, and it would help
clarify why gravity appears to be so much weaker than the other fundamental
forces.

Still, there's no solid confirmation yet. And several physicist still doubt
that these universes exist.

Brian Greene, a
theoretical physicist at Columbia University, said while arguing about the
multiverse theory "I only believe in things with concrete, verifiable
experimental evidence supporting them, and that's not the case right now with
the concept of parallel universes,”

The key, however, is that
scientists are getting away from just philosophical considerations of the
multiverse theory. They're truly putting the notion of multiverse to the test.
Some are still betting on the more fundamental and so far untestable sorts of
multiverse theory.
